High power energy harvesting becomes significant #tech #news

High Power Energy Harvesting: Off-Grid 10W-100kW 2016-2026 is the title of a new IDTechEx report examining a newly significant off-grid energy market. True, the sales of small off-grid wind turbines is a tiny fraction of the $100bn market for wind turbines overall but this is just one of the electrodynamic ways of generating electricity where it is needed using ambient energy. Think of regenerative braking of trains, buses, trams, cars and so on using generators and motors working backwards. Indeed Torque Assist Reversing Alternators (TARA) are being prepared in the UK for use in conventional cars. The humble bicycle dynamo has been followed by regenerative soaring of Electraflyer aircraft and regenerative sailing of Beneteau, Milper, Rensea and other sea-going boats with thrust propellers that work backwards to generate electricity. Diesel will be eliminated from sailing ...
